ForgeFix General Purpose Twin Thread Screws 1 1/2" x 7 Zinc Plated Box 200

These Forgefix General Purpose Pozi Compatible Screws with Countersunk heads are designed to provide increased durability thanks to their zinc plating. As one of the most popular general-purpose screws available, they are suitable for a wide range of applications involving different materials.

Application

These screws are ideal for various ironmongery, electrical, and plumbing applications. They can also be used in conjunction with various screw cover caps, making them versatile for diverse projects. The zinc coating prevents oxidation of the protected metal, creating a longer-lasting finish. This protective layer forms a barrier and acts as a sacrificial anode if damaged, ensuring extended durability. When exposed to air, the zinc reacts to form zinc oxide, a fine white dust that does not compromise the substrate's integrity, unlike iron oxide. This zinc oxide can act as an additional barrier to further oxidation, similar to the protection afforded to aluminium and stainless steels by their own oxide layers.

Pozidriv Design

The Pozidriv screw differs significantly from the classic Phillips cross-head screw. While both may appear similar, the Pozidriv design features four additional points of contact and lacks the rounded corners found in Phillips screws. This unique design allows the Pozidriv to resist cam-out when used with the appropriate tooling, enabling greater torque application. You can easily identify a Pozidriv screw by the embossed line at a 45-degree angle to the slots for the driver on the screw head.

The countersunk head of these screws is specifically designed to sink flush with the substrate, providing a smooth surface finish. The twin thread feature enables an easy start during insertion, making these screws user-friendly. Additionally, the extra deep insert bit recess allows for a quicker and simpler insertion process, contributing to a firmer, more positive drive. The twin thread, combined with a special wax coating, enhances the speed and ease of insertion, while also providing increased holding power.
